If you are willing to let go of romanticism and fear, you can find algorithms for getting laid by searching Google. I personally know a few people that have implemented those algorithms and they all succeed frequently. I know a guy whose marriage was founded (unknowingly to his wife) on such Google-found advice.
There is a reason "How to Win Friends and Influence People" is one of the best-selling books of all time. Reading just that one book will get most people all the sex and "friends" they want if they follow its advice. I recommend everybody to try it if they are feeling really down on themselves or really frustrated. It can be a life-changing experience.
Unfortunately, there are a lot of downsides to reading an (e-)book about getting laid or making friends too. Sometimes you have to be careful what you wish for.
